FEBRUARY 21, 2008 -- Micron Optics Inc. has enhanced its current line of Fabry-Perot tunable filters with a high finesse tunable filter, a widely tunable filter with PM fiber, and an improved bandwidth variation for the FFP-TF2.
The Micron Optics Fabry-Perot tunable filter, the FFP-TF2, with a finesse value of 16,000 is now commercially available. This more than triples previously offered standard finesse values, claim company representatives. These very high finesse filters can be used for applications requiring filter response curve with a sharp top and very steep sides. Typical contrast values are at 80 dB. Certain applications that previously required two filters cascaded to achieve this high finesse will now only need one of these filters.
Users can also select a widely tunable filter equipped with PM fiber. Micron Optics says it was the first company to introduce a one-peak 340-nm-wide tuning range Fabry-Perot filter. Now this same filter is also available in a PM fiber version.
Micron Optics says it has also made significant improvements in the bandwidth variation of the FFP-TF2. Bandwidth variation over a single order is now a tight +/-5%, which is unheard of in widely tunable filter performance, claim company representatives.
